The 'per capita demand' includes which components of water use?
Choose the correct answer
Only drinking water (2 L/c/d)
Domestic + commercial + industrial + public uses + losses — all categories of water use in a town
Only irrigation use
Only industrial water
Correct Answer
B. Domestic + commercial + industrial + public uses + losses — all categories of water use in a town
Why is this the answer?
Per capita water demand includes: (1) Domestic (drinking, cooking, bathing, flushing): 70–80 L/c/d; (2) Commercial: 5–10%; (3) Industrial: 5–10%; (4) Public (firefighting, fountains, parks): 5%; (5) Losses (leakage, unaccounted): 15–25%. Total per IS 1172 for towns = 135 L/c/d min; cities = 150–200 L/c/d.
